Bone types:
Cortical: dense outershell, 80%
Cancellous: spongious bone encased by the cortical bone
Wolffs law
Bone reformation occurs in response to the stresses that is placed on it
Vertebrae in each section of the spine
Cervical- 7
Thoracic- 12
Lumbar-5
Nerve root function: dorsal and ventral
Dorsal- sensory
Ventral- motor
Vcf
Vertebral Compression Fracture: vertebral bone in the spine collapses, causing the spine to shorten and often fall forward
How many VCFs annually and how mean clinically treated
700,000 annually
1/3 treated
Osteoporosis
Skeletal disorder characterized by reduction in mass of bone and increase in risk fracture
Osteopenia
Bone condition in which concentration of minerals is diminished and bone mass reduced
Similarities and differences between osteoporosis and osteopenia
Similarities: increased risk of fracture from decreased bone mass
Differences: osteopenia has de-mineralized bone, while osteoporosis is normal mineralized bone p
NIH
National institute of health; one of the worlds most foremost medical research centers
Risk factors for osteoporosis
Genetic: family history, race
Behavioral: cigarette smoking, excessive alcohol, inactive lifestyle
Nutritional: low calcium diet, low body mass
Osteoblast vs Osteoclast
Osteoblast- creates or builds bone
Osteoclast- destroys bone
This reformation is in response to the stresses applied on it (Wolffs Law)
Treatments for osteoporosis
Non-pharmaceutical
adequate calcium intake, adequate vitamin d intake, regular weight bearing activity, reduced alcohol/ smoking
Label vertebral body
Look at picture
VCFs vertebral deformations:
Crush fractures: collapse of entire vertebral body
Wedge fractures: collapse of anterior or posterior of vertebral body
Bioconcave fracture: collapse of central portion of both vertebral body end plates
